Ch.14: Comparative Study on Bioactive Compounds of Leaves of Carica Papaya, Catharanthus Roseus, and Callistemon Viniinalis with Current Prospects

ABSTRACT: Plants are considered a good source for the exploration and discovery of new pharmaceutical compounds as well as medicines. It can be a potential drug for humans as it acts as an intermediate for the synthesis of useful medicines. Plants possess various Phytochemical with several bioactivities such as anti-inflammatory,  antioxidant, and anticancer. Therefore, the phytochemical characteristics of medicinal plants need to be studied. Some such medicinal plants are Carica papaya, Catharanthus roseus, and Callistemon viminalis. The Study revealed the presence of major bioactive compounds like Alkaloids, Carboxylic acids, Carbohydrates, Phenols, etc. in the three plants. Flavonoids are absent from the leaves of Catharanthus roseus. Steroids were absent only from the Catharanthus roseus. Tannin was absent from the Callistemon viminalis leaves. Saponins were absent from Carica papaya and Callistemon oiminalis. Quinones were absent from the Carica papaya and Catharanthus roseus. The FTIR technique has been used to monitor and understand the chemical and surface chemistry of leaf extracts of these three plants.
